Brazing is a metal-joining process in which two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal. Brazing differs from welding in that it does not involve melting the work pieces. Brazing differs from soldering through the use of a ...
Active alloy. Can be used for brazing ceramics, metal-ceramics, graphite, diamond, corundum, sapphire, ruby. Needs at least 850 °C for wetting ceramics, higher temperatures improve wetting. For use under argon or vacuum, in vacuum silver may evaporate above 900 °C. 19.5: 72.5: 3: In 5: Ag 96 Ti 4: active 970 [98] – BrazeTec CB2. Active alloy.
Soldering and brazing are thought to have originated very early in the history of metal-working, probably before 4000 BC. [2] Sumerian swords from c. 3000 BC were assembled using hard soldering. Soldering was historically used to make jewelry, cookware and cooking tools, assembling stained glass , as well as other uses.
Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating. In induction heating, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current from an induction coil .

An inexpensive alloy that is easily cast and worked, spelter was used from the 1860s in the manufacture of candlesticks, clock cases, tableware, and light fixtures. In the early 20th century, sculptors such as Jacques Limousin used spelter heavily in their manufacture of Art Nouveau and Art Deco figurines and other ornaments.
Hydroforming is capable of producing parts within tight tolerances including aircraft tolerances where a common tolerance for sheet metal parts is within 0.76 mm (1/30th of an inch). Metal hydroforming also allows for a smoother finish as draw marks produced by the traditional method of pressing a male and female die together are eliminated.
Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added [ 1 ] process involving the creation of machines, parts, and structures from various raw materials.
